Metacat

Added support in ResourceHandler for the /formats collection. Added listFormats() and getFormat() method, both of which call CNCoreImpl methods to handle the call.

When calling SystemMetadata.getObjectFormat(), return the string value of the ObjectFormatIdentifier rather than ObjectFormat.toString() (which no longer returns the fmtid string).

organize imports so that it is clearer what dependencies exist on the D1 jars

Merged in the D1_0_6_2_BRANCH changes that include the transition from ObjectFormat calls to ObjectFormatCache calls.

include CNCore implementation - only registerSystemMetadata is implemented at the moment. also - updated d1 jar (0.6.2) should be used since that is where the method is defined.
would like to consider making ResourceHandler more modular - seems like it does A LOT of different things

do not use XML files for storing SystemMetadata - use DB tables only.

In order to sync up with DataONE 0.6.1 changes, I'm backing out ObjectFormatService changes temporarily in Metacat. Most functionality will be rolled back in using the DataONE 0.6.2 tag, but some methods in ObjectFormatService (such as getListFromDisk()) will be moved into d1_libclient_java.

Changes in the DataONE ObjectFormat class deprecate the convert() method, and we're now using Metacat's ObjectFormatService to look up object format attributes. The following changes replace ObjectFormat.convert() with ObjectFormatService.getFormat() in several classes....

committing changes related to the new restservice update specification (newPid vs. obsoletedGuid)

Use SystemUtil.getContextURL() in ResourceHandler to construct the DataONE service URL (rather than direct calls to PropertyService). This handles http and https URLs, and strips the :80 or :443 for the well known ports.
